The average yearly temperature is freezing, but it can get as high as 8°C (46°F) in the austral summer and as low as -50°C (-58°F) in the austral winter.
Due to the partial melting of snow in summer due to above freezing daytime temperatures, animals as well as limited plant life (moss, lichens, and worts) are able to thrive during the warmer months of December, January, and February. Mean monthly temperatures range from −15.1 °C (4.8 °F) in June to −1.7 °C (28.9 °F) in December. [18]
